JOHN SIEGEL, OF MONTREAL, CANADA.

HEEL-PROTECTOR FOR RUBBER SHOES.

SPECIFICATION forming part of Letters Patent No. 437,049, dated September 23, I890.

Application filed May 1, 1890- Serial No. 350,398. (No model.)

To aZZ whom, it may concern:

Be it knowngthat I, JOHN SIEGEL, of the city of Montreal, in the Province of Quebec, in the Dominion of Canada, have invented certain new and useful Improvements in a Heel-Protector for Rubber Shoes; and 1 do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part hereof.

My invention, which will be hereinafterfully set forth and claimed, relates to attachments to heels of rubber shoes or boots.

The object of my invention is an attachment to the heels of rubber shoes or boots that is readily attachable and detachable, and by means of which the wear and tear of the rubber heel are prevented, and that will at the same time act as a preventive against slipping on ice and other slippery surfaces.

Figure 1 is a perspective View of a rubber shoe having my heel-protector attached. Fig. 2 is a perspective View of my protector. Fig. 3 is a side View of my protector. Fig. 4 is a longitudinal section of the same, and Fig. 5 is a cross-section of the same, showing the heel of the rubber concaved by lateral compression when placing the protector in position.

My heel protector is made of thin stiff metal, preferably sheet-steel, and may be produced in dies or cast. It consists of a plate A, conforming to the shape and size of the fiat portion of the heel, slightly narrowernear the instep than farther rearward, provided with a number of outwardly-projecting indentations a to cause an exterior roughness, and may have perforations a" to decrease the weight of the protector and to afford direct bearing-surfaces to the rubber. Said plate is curved at the edge aadjacent to the instep to conform to the shape of the heel at the instep, so as to cause a close fit of said edge to the material of the rubber. Around said plate A, except at the instep edge, is a raised rim or margin B, formed integrally with said plate or secured to it and conforming generally to the outline of the rimof the rubber heel, care being taken that the width across the plate A between the flanks of the rim B is not greater, but rather less, than the breadth of the rubber heel at that point, so that the rubber will completely fill and be tightly squeezed between said rim. The rear 12 of the rim may be made higher than the other portions, and be provided with a perforation 1), adapted to engage the projection r, with which the heelof some rubbers are provided. The flanks of the rim B may be provided with an inwardly-projecting crimp or crease b to engage a corresponding indented line usually existing at the edge of the rubber heel-plate, or the crease may project outwardly to engage a projecting ridge on the rubber. Said flanks may also be provided with perforations 19". Below said crimp or crease the rim maybe provided with inwardly-proj ecting indentations b to engage the edge of the rubber heel-plate.

In placing the protector on the heel of the rubber the latter is compressed laterally to assume a concave form, and the protector is placed in position on it, as shown in Fig. 5. The concavity is then flattened out by pressme from the inside of the rubber, thus pressing the edges of the heel outward and tightly engaging the rim of the protector.

I claim as my invention- 1. In a heel-protector, the combination of a plate A, conforming to the size and shape of the heel to be covered, and having the curved instep edge a and provided with perforations a, and the rim B, having creases b,perforations 17, and indentations b substantially as set forth.

2. In a heel-protector for rubbers, the combination of a metallic plate conforming to the size and shape of the heel to be covered, but slightly smaller and drawn in at the instep, a curved instep edge conforming to the curve of the instep, so as to fit the same closely, and a rim at a right angle to said plate, extending around said plate from one end of said instep edge to the other and provided with a ridge or ridges, substantially as set forth.

3. A heel-protector consisting of a plate A, conforming to the size and shape of the heel to be covered, but slightly smaller and drawn in a little at the instep, and a continuous integral rigid rim or flange B, extending all around said plate, from one corner of the instep to the other, substantially as set forth.

In testimony whereof I have signed in the presence of the undersigned witnesses.

J. SIEGEL.
